like Running is training for a marathon. While training, his volume of air in each breath is 1.5 L and he takes approximately 15 breaths per minute. His total lung capacity is 5500 mL and his residual volume is 1500 mL. Ilike has a blood pH of 7.2 and his cardiac output is 4.95 L/min. His heart is pumping 172 times per minutes. Finally, his expiratory reserve volume is 750 mL. In order to increase his performance, Ilike wants an analysis of his current exercise values. Please determine the following based on the information listed above. Blank 1: Tidal Volume Blank 2: Vital Capacity Blank 3: Ventilation Blank 4: Stroke Volume Blank 5: Inspiratory Reserve Volume:
During maximal aerobic exercise, exercise-induced arterial hypoxemia may result in elite endurance athletes due to which of the following? reduced venous return leads to decreased pulmonary capillary flow rate transit time through the pulmonary capillaries is much shorter oxygen diffusion capacity is no longer calculated using capillary mean PO2 lower venous O2 content increases the PO2 gradient
Altitude effects on exercise are caused mainly by increased CO2 production due to the physiological response to low pressure the increased influence of nitrogen gas at higher altitudes lowered 02 partial pressure the direct effect of low pressure on breathing
Is there an important difference between training at high altitude and taking EPO? Can EPO be safe (and is the same as high training) if the users monitor the level of red blood cells and do not overuse it?
In a woman with body mass 70 kg blood quantity is 4.9 liters; hematocrit is 32%, the quantity of erythrocytes is 3.0*10^12/l, hemoglobin is 105 g/l color parameter is 1.0, the minimum osmotic resistance of erythrocytes is 0.38%NaCl; the maximum osmotic resistance of erythrocytes is 0.34%NaCl Such blood analises testifies first of all about: A. the water excess in the organism B. the lack of water in the organism C. osmotic hemolysis of erythrocytes D. chemical hemolysis of erythrocytes E. the lack of iron in blood plasma
Referring to the loading and unloading of oxygen from hemoglobin (as illustrated in the figure), which of the following statements is correct? Oxygen Dissociation Curve.png Group of answer choices When a person in ventilating at rest, 75% of hemoglobin is still oxyhemoglobin The percent saturation of hemoglobin is higher at higher partial pressures of oxygen A decrease in the pH of the blood would promote unloading oxygen from the hemoglobin All of these are correct

What are the average hematocrit values (%) at low altitude and then after the subject trained at high altitude for 2 months? 2. Did average hematocrit increase, decrease, or not change after training at high altitude for 2 months? 3. What are the average hemoglobin values (g/100 ml) at low altitude and then after the subject trained at high altitude for 2 months?
Draw three separate oxygen-hemoglobin dissociation curves and then use arrows to show the change in oxygen saturation of most hemoglobins when: 1. deoxygenated blood enters the capillaries in the lungs. 2. oxygenated blood enters the capillaries in muscle tissue at rest. 3. oxygenated blood enters the capillaries in muscle tissue during vigorous exercise.
What is the rational for the benefits of LHTL training? O high altitude alters blood composition, while low altitude allows maximum intensity training high altitude makes training harder, and low altitude enhances blood composition high altitude promotes better rest and low altitude allows more intense training O high altitude enhance hematocrit, and low altitude increases Hb concentration
Which of the following is the concentration of hemoglobin-bound oxygen in the blood when the heme is fully saturated? 8500 uM 8630 uM 2200 uM 8800 uM
